This M9 CO2 powered airsoft blowback guns use CO2 or green gas magazines. While there are several types of gas-powered airsoft guns, the most popular are the Gas-Blowback guns (GBBs). The GBB allows a realistic, semi-automatic firing of the gun by employing either an on-board, or magazine-stored gas storage system. Basically, the same compressed air that propels the BB out of the bore is harnessed to cycle the slide back (hence: blowback). This creates the realistic "recoil" by cycling the slide/upper receiver back-and-forth while firing the gun. This system gives the hand-held gun the capability to empty a magazine as fast as you can pull the trigger, and just as easily reload the gun by inserting a fresh magazine. Needless to say, this feature holds tremendous appeal for the "simulations'".
